Modulators

Multi-channel

The modulator has 8 audio/video inputs and one RF output combining eight separate working channels selected within the whole TV band (ch. 1-12, S1-S38, 21-69, with 5.5 or 6.5 MHz sound subcarrier - B/G or D/K standard). The modulator is mainly used for distribution of CCTV images within antenna systems.

In SMATV/MATV systems the device has to cooperate with ZG-401/601 channel amplifiers (ordered for the operating channels). The amplifiers eliminate interferences and adjust signal levels to those required in a distribution network.

Power supply has to be bought separately ( M1818 with 5V/1000mA output).
